Step 6: Cut Up the Soda Can

The soda can will provide the material for the pinhole. The advantage of this is that you can make different pinholes and swap them out of the camera body. Different hole sizes will produce different effects. Also, making the edges of the pinhole jagged will create a "rough edged" photo you take with the camera. Also, if you mess up, you can have a second chance.

Cut a small square out of the soda can (can be any dimension, but must cover the 1/8 hole in the tin), and find the center of the square using the ruler. 
To Worcester think tank any where from 10-20sec on a bright day and 15-30secs on a cloudy day. Although each camera may very. I took mine with two different camera and my second box took almost double the amount of time.
I built one of these cameras about 4 months back. They work well I even played with a duel exposer
<p>I just made these with six students in an optics class. How long do you recommend we keep the pin hole open to expose the film or paper inside once we want to take a picture?</p>
<p>any instruction on how to make a tracing style camera obscura? is it then same concept as the pinhole but with an longer box and a bit of glass and mirror?</p>
Magnets have no negative effect on film, FYI.
Forgive me for sounding stupid...but how do i take a picture with this? Do i need to load the film and cover the pinhole? then take the cover of the pnhoe for the image to process? how long need i leave the pinhol uncovered etc?
personally i don`t use pin hole cameras i just use digital
A camera obscura (sometimes spelled oscura) isn't a device, it's a room - literally a 'darkened chamber'. Originally it was observed that a small hole in an otherwise covered window would project an inverted image onto an opposite wall, but the term came to be used for a more complex room with a lens in the ceiling and a circular reflector on the roof above which projected a 360 degree panorama of the surrounding landscape onto a circular table below. Typically the camera oscura would be at the highest point in the town and you could go there to observe the entire town in real time, much like viewing a live satellite surveillance image. There is still an existing camera oscura in Edinburgh, Scotland, at the top of the Royal Mile near Edinburgh Castle, and it is a very popular tourist destination. Unless the meaning of the word has drifted over the years, I don't think it is correct to use this term for a simple pinhole camera.
Camera obscurae come in all sizes.&nbsp; Desktop sized camera obscurae have existed for centuries, and were generally used to take tracings of well-lit objects.<br> <br> A pinhole camera is a type of camera obscura, specifically a small (usually portable) camera obscura without a lens, and with film to capture the image instead of a projected surface for drawing as with other small camera obscura.&nbsp; They operate on the same principle.<br> <br> On the flip side, a number of building sized camera obscurae were lens-less, utilizing the pinhole effect to project an image on the rear wall of the building.
could you use polaroid film like the one that fujifilm now makes instead of film because this instructable does https://www.instructables.com/id/Pinhole-Camera/ <br>and I was wondering if it fit could it be done??? thanks
This is a great instructable. I have got to get some photo paper, developer, and fixer. They have direct positive paper that you can print onto with pinhole cameras without having to use a negative to capture the image. Cool stuff.
You can make a finer/better pinhole by placing the aluminum on something a little soft. like cardboard. push the pin into the metal (just enough to make a small bump, not poking through the can) then take some medium/fine sandpaper and sand down the bump. then poke it with the pin again make a new teeny bump, and sand it too usually at this pint the metal will be incredibly thin, and you can easily drill with a needle a teeny hole. (you want just the point to pierce the aluminum. you can then blacken it with soot from a candle flame (holdin git with tweezers. <br><br>ive also used foil tape for making the pinholes (same technique) but its already thinner. <br>you can see some of my blueprint photography pinholes here. <br>http://www.flickr.com/photos/killbox/5615030902/<br>and<br>http://www.flickr.com/photos/killbox/6184594300/
That's a great idea, and I will try that next time. I feel that the size of the pinhole can also be a creative variable because it can be manipulated to create certain effects with the film.
wheres the camera?
The camera is the Altoids box. The pinhole in the lid is the aperture that lets the light in, and the distance from the aperture to the film acts like the focal length. By peeling the tape off and putting it back on, you can work the shutter. I will be adding another Instructable shortly on how to make a more effective shutter. Does that satisfy your question?
I like how it looks like old fashion pictures.
